INTRODUCTION

Living and studying the river otter (Lontra canadensis) in southwest Florida and compiling the bibliography for Lontra canadensis caused me think more about this otter species’ counterpart, the Neotropical river otter (Lontra longicaudis), in Mexico and Central and South America. I wanted to know more about the biology, ecology, and conservation of the Neotropical river otter and wish to learn about and compare research studies and methodologies between these two species. This bibliography was primarily compiled to aid undergraduate and graduate students and colleagues in the New World seeking information on the Neotropical river otter.

What happens to the future of this bibliography? This is up to you scientists investigating Lontra longicaudis! Please realize it is not difficult to do a literature search on a species. All you need to do is go to Google and type in year followed by the scientific name, e.g. 2019 Lontra longicaudis –you need not italicize the scientific name. Then click the year and scientific name. Many publications will appear and all you do you click on them and the article will appear and you copy down the information required for a citation. You may need to do a little searching to get the citation information. Publications will appear from most years prior to your “search year”. If you wish you can do a search with an earlier year.

A bibliography needs formatting structure. I followed the formatting as I had done with the bibliography on the North America river otter (Lontra canadensis). For this bibliography, I believe the first formatting challenge is the language used in the bibliography. The citations in the scientific literature are in either in Portuguese, Spanish, or English. These citations are provided in the bibliography in the language used in the publications found in the literature search. Spanish or Portuguese citations may have an italicized English translation, in brackets, following the publication title. No attempt was made to translate a citation from English to Portuguese or Spanish as the next author(s) can do that. Only a few publishers will provide an English translation. Google Translate was used for the translations. Some citations are lacking the year of publication and the name of the journal in which they were published. These citations were searched for on the internet to find the year and publication information. The use of the scientific name singularly in the title is always italicized. If the common name is used and followed by the scientific name, then the scientific name appears in parentheses. Author formatting is another challenge. A variety of formats can be seen in the scientific literature. In this bibliography and the Lontra canadensis bibliography the initials of the first author follow the author’s last name and the initial(s) of the first name(s) of the additional authors precedes these authors’ last names. The tile of the journal or publication is always italicized and the volume number is in bold type and the issue number, if available, is in parentheses. The pages of the citation, if indicated in the literature, always follow the volume and issue numbers and are separated by a colon.
